QualiAO™ Series: ISO 188, 1817, ASTM D471 & D865 Heat-Aging Solutions
Aging Ovens are precision laboratory instruments engineered to simulate years of natural heat-aging exposure on materials such as rubber, plastics, leather, and fabrics — in days or weeks rather than years. By holding samples at carefully controlled elevated temperatures for prescribed durations, aging ovens reveal exactly how a material will discolor, split, shrink, lose elongation, harden, and ultimately fail under long-term thermal exposure. The result is critical predictive data that supports product service-life forecasting, formulation development, regulatory compliance, and the difference between products that last decades and products that fail in months.
Qualitest offers a comprehensive aging-oven portfolio covering every laboratory configuration: the Block Oven – Aging Oven (built by Gibitre, Italy) for precision aluminum-block test-tube aging of elastomeric samples in air and liquids — fully conforming to ISO 188, ISO 1817, ASTM D471, ASTM D865, and EN 681-1 standards; the compact QualiAO™-BL1 Benchtop Aging Oven, ideal for space-constrained labs needing accurate heat-aging on rubber, plastics, leather, and fabrics; and the floor-standing QualiAO™-M1/L1 Series, delivering production-volume hot-air aging for high-throughput QC and product-development programs. Every QualiAO platform features high-precision PID temperature control, multi-point calibration, intuitive LCD control panels, and consistent temperature distribution across the entire working volume.

Why Choose Qualitest for Your Aging Oven Needs
Qualitest is a globally recognized supplier of advanced rubber, polymer, and materials-testing instruments, serving customers across more than 80 countries with one of the most comprehensive aging-oven portfolios available worldwide.
Three-Tier Portfolio — One Trusted Source
From the compact QualiAO™-BL1 benchtop for space-restricted laboratories, through the high-capacity QualiAO™-M1/L1 floor-standing units for production-volume aging, to the precision Gibitre-built Block Oven for hot-air and liquid-immersion test-tube aging — Qualitest offers a coordinated portfolio that matches every laboratory size, throughput, and compliance requirement.
Premium Gibitre Engineering
The Block Oven – Aging Oven is developed and manufactured at Gibitre's state-of-the-art facility in Italy. All mechanical components are crafted in-house using advanced CNC machines, components and sensors are sourced from reputable brands, and every production phase is overseen by internally trained personnel for unmatched build quality and measurement reliability.
Full International Standards Compliance
Qualitest aging ovens meet the most demanding global standards — ISO 188 (rubber accelerated aging and heat-resistance), ISO 1817 (effect of liquids), ASTM D471 (rubber property/effect of liquids), ASTM D865 (rubber deterioration by heating in air, test-tube enclosure), and EN 681-1 (elastomeric pipe-joint seals). Calibration certificates are traceable to primary standards.
Precision Temperature Control
Every QualiAO™ platform delivers high-precision PID temperature control, multi-point calibration, and consistent temperature distribution across the working volume — critical for repeatable aging results across long-duration test campaigns. The Block Oven uses PT 100 thermal probes for laboratory-grade thermal accuracy at 70 °C, 150 °C, 200 °C, and 250 °C.
Versatile Air + Liquid Aging
The Block Oven uniquely supports both hot-air aging (ASTM D865) and liquid-immersion aging (ASTM D471, ISO 1817) — with optional water-cooled reflux condensers attachable to each individual test tube, preventing volatile-liquid evaporation and maintaining test-fluid composition throughout long aging cycles.
Cost-Effective Value & Global Support
Qualitest delivers premium aging-oven performance at a transparent, competitive price point — backed by global service, training, ISO 1817 calibration support, spare parts, and accessories. With worldwide presence, expert support is always within reach.
Age With Precision. Predict With Confidence.
Every material that goes into service will age — the only question is whether you discover how before your customers do. A poorly characterized aging profile means rubber seals that crack mid-service, plastic housings that fade and embrittle, footwear that loses its bond, and infrastructure components that fail under thermal cycling. The laboratories that consistently deliver durable, regulator-compliant, customer-satisfying products are the ones equipped with aging ovens built for precision, repeatability, and full international-standards compliance — and the Qualitest QualiAO™ portfolio gives you exactly that.
Whether you are developing the next generation of automotive elastomers, verifying coatings for an architectural specification, qualifying rubber pipe seals to EN 681-1, or running fundamental polymer-aging research, Qualitest has the aging-oven platform engineered to meet your exact needs. From the compact QualiAO™-BL1 to the floor-standing M1/L1 series and the precision Gibitre Block Oven, every Qualitest aging oven delivers world-class accelerated-aging performance backed by industry-leading service and support.
